Phenalkamines Drolite portfolio is defined by its versatile chemical architecture, utilising the unique long-side-chain structure of cardanol to provide an ideal balance of fast curing and high flexibility assisting formulators to achieve rapid (return-to-service) even in sub-optimal field conditions. Phenalkamines are inherently surface-tolerant, providing a "built-in" safety margin when substrate preparation is limited. By selecting specific grades based on amine value and viscosity, phenalkamines manufacturers can optimise their processing windows for everything from ultra-low viscosity injection grouts to high-viscosity structural putties ensuring Total Cost of Quality is minimised through reduced surface preparation labour, faster project completion, and a significantly lower risk of failure in moisture-prone environments. We are an established manufacturer of CNSL-based Phenalkamines series, ensuring consistent purity and reactivity profiles across the Drolite Phenalkamines Polymers Series. We provide a comprehensive range of surface-tolerant curing agents with full technical (Viscosity/Amine Value/AHEW) and supporting quality assurance documentation (COA/TDS/SDS). Our products are optimized for high-solid and solvent-less formulations, offering superior performance in marine and heavy-industrial protective sectors. We ensure reliable lead times from R&D sampling to 10MT+ commercial supply, enabling partners to lead in high-durability infrastructure protection.

Chemical Properties & Specifications
Industry standard for ballast tanks, ship hulls, and offshore platforms. These hardeners provide exceptional corrosion resistance and can be applied in high-humidity or submerged conditions
Designed to maintain high reactivity in cold climates, allowing for full mechanical cure at temperatures as low as 0°C (32°F), where standard polyamides fail to react
Exceptional moisture displacement properties enable successful application on wet concrete or damp steel surfaces, preventing osmotic blistering and bond failure
Chemically inert barrier against aggressive reagents, organic acids, and petroleum products in industrial containment systems
Facilitates the formulation of low-VOC, high-build coatings that meet stringent environmental regulations without sacrificing application speed or film integrity
Standard polyamides are moisture-sensitive and can lead to poor adhesion or "blushing" on damp surfaces. Drolite Phenalkamines are chemically hydrophobic. The long aliphatic side chain of the CNSL backbone displaces moisture from the substrate, ensuring a robust mechanical bond even on wet concrete. This technical advantage significantly reduces project delays caused by inclement weather or high humidity.
Phenalkamines are Mannich-base curing agents. The phenolic hydroxyl group in their structure acts as a built-in catalyst, significantly lowering the activation energy required for the epoxy-amine reaction. This enables the polymer matrix to achieve full cross-link density at temperatures as low as 0°C, making them essential for winter-grade industrial maintenance coatings.
Unlike many curing agents that require precise stoichiometry to avoid "soft-spots," phenalkamines are relatively forgiving of slight mixing ratio variations. This provides a critical safety margin for manual field applications (like hand-applied putties or spray coatings in shipyards), ensuring consistent mechanical performance even under difficult site conditions.
We bridge the gap between heavy-duty performance and global compliance. Every shipment is accompanied by a batch-specific Phenalkamines series COA/TDS and a GHS-compliant SDS. Our phenalkamine range is REACH registered, providing Sourcing Managers with the necessary documentation to clear international technical audits for maritime and oil & gas infrastructure projects.
We specialise in large-scale industrial supply with a standard lead time of 7–8 Weeks for volumes up to 10MT. Products are typically supplied in 200 Kg MS/HDPE Drums or 1,000L IBCs, offered Ex-Works to ensure streamlined global logistics for offshore and infrastructure projects.
